With some devices it seems like you are constantly replacing batteries. Super inconvenient, and also environmentally unfriendly. Fortunately, you can solve this with rechargeable batteries. The Philips battery charger comes in handy here. The universal USB charger offers space for 2 AA rechargeable batteries and 2 AAA rechargeable batteries. In addition, you can use the battery charger anywhere in the world thanks to a micro USB output. Included with the Philips battery charger are 4 Ni-MH batteries: 2 AAA batteries and 2 AA batteries. Ni-MH batteries are perfect for devices that consume a lot of power in a short time. Think of cameras, but also game controllers or flashlights. The advantage of these batteries is that you can charge them. This extends their lifespan and they are generally more environmentally friendly than non-rechargeable batteries.
